Most common pathologies in humans are not caused by the mutation of a single gene, rather they are complex diseases that arise due to the dynamic interaction of many genes and environmental factors. This plethora of interacting genes generates a complexity landscape that masks the real effects...

Purpose – The purpose of this paper is to explore the question of whether the differences between meaning in philosophy and meaning in information retrieval (IR) have implications for the use of philosophy in supporting research in IR. Design/methodology/approach – The approach takes the...

If one information service is more informative than another, then any agent values it more. In fact, the opposite implication is also true, and this characterization is the celebrated theorem of Blackwell. We present here a short proof. This is a correction of our earlier attempt.

A numeric method to characterize phase transitions is presented, explained and applied to a two-dimensional disordered system that can be thought of as a diluted ferromagnet or an Edwards–Anderson model near the ferromagnetic limit. A computer simulation is implemented to define a time series...

"In symmetric commons dilemmas, peer sanctioning, i.e. the possibility to gather information about the resource use of others and to sanction overuse, can be an effective structural solution in terms of resource conservation. However, most real world commons are characterized by structural...

In many Internet commerce applications buyers can easily achieve anonymity, limiting what a seller can learn about any buyer individually. However, because sellers need to keep a fixed web address, buyers can probe them repeatedly or pool their information about sellers with the information...

Firms with private information about the outcomes of production under uncertainty may face capital (liquidity) constraints that prevent them from attaining efficient levels of investment in a world with costly and/or imperfect monitoring. As an alternative, we examine the efficiency of a simple...
